Abstract
The utility model relates to a speed change gear box, comprising a box body, an input shaft and an output shaft; the input shaft is provided with an input duplicate gear in axial gliding manner; the output shaft is provided with an output duplicate gear in axial gliding manner; a transition shaft is installed between the input shaft and the output shaft; and the transition shaft is provided with a first duplicate gear and a second duplicate gear. The utility model uses the duplicate gear to change the gear and the speed so that four-gear speed change can be formed; the gear is changed through a guide shaft and a dialing fork, and the operation is convenient and flexible; the guide shaft is provided with a limiting clamp ring to change the gear rightly; by using the position-change straight gear, the tooth shape of the gear-change surface is in arched converse angle so as to increase the slide rate of gear, thus the engagement is more smooth and the noise is lower; each duplicate gear is separated, thus the processing, installation and maintenance are more convenient; the box body is made from HT250 integrally cast, thus the box body has good vibration resistance and bearing performance, and the rate of leakage is reduced; the box body uses the technology of resin sand-casting; the outer surface of the box body is smooth and flat; and the speed change gear box is beautiful.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of speed-change gear box.
Background technique
At present, electrician's cable industry draws general employed shift speed change gear-box because gear box structure is provided with unreasonablely, so have mostly that noise is big, vibration is big, a problem such as oil impregnate, bearing capacity be low easily, can't satisfy the high request of modern industry.
The model utility content
The purpose of this utility model is to provide a kind of speed-change gear box smooth and easy, that noise is low, vibration is little, bearing capacity is high that meshes.
The technological scheme that realizes the utility model purpose is: a kind of speed-change gear box has casing, input shaft and output shaft; Endwisely slip on the described input shaft and be provided with the input duplicate gear, endwisely slipping on the output shaft is provided with the output duplicate gear, is provided with transition axis between input shaft and the output shaft, and transition axis is provided with first duplicate gear and second duplicate gear.
Be provided with the input axis of guide parallel and export orientation axle in the casing of above-mentioned speed-change gear box with input shaft, endwisely slip on the input axis of guide and be provided with the input shift fork, endwisely slip on the export orientation axle and be provided with the output shift fork, described input shift fork and the clamping of input duplicate gear, output shift fork and the clamping of output duplicate gear.
Be equipped with spacing collar on the input axis of guide of above-mentioned speed-change gear box and the export orientation axle.
Each gear of above-mentioned speed-change gear box all adopts the displacement spur gear, adopts split-type structural, the equal circular arc chamfering of gearshift face profile of tooth of each gear.
The integral piece of the casing of above-mentioned speed-change gear box for adopting the cast inblock of HT250 material resin sand casting technique to form.
The utlity model has following characteristics: (1) the utility model adopts the duplicate gear shift speed change, can form four-speed gear shift; (2) shift gears flexible and convenient operation by the axis of guide and shift fork; (3) spacing collar is set on the axis of guide, gearshift puts in place; (4) adopt the displacement spur gear, the equal circular arc chamfering of gearshift face profile of tooth has increased the sliding ratio of gear, meshes more smooth and easyly, and noise is lower; (5) each duplicate gear adopts split-type structural, processes, installs, safeguards more convenient; (6) casing adopts cast-in-block HT250 material, and cast inblock forms, and has good seismic resistance and load-carrying properties, and has reduced the probability of seepage; Casing adopts the resin sand casting technique, and box outer surface is bright and clean smooth, and machine shape is attractive in appearance.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a structural representation of the present utility model.
Embodiment
(embodiment 1)
See Fig. 1, the utlity model has casing 100, input shaft 200 and output shaft 300; The integral piece of casing 100 for adopting the cast inblock of HT250 material resin sand casting technique to form, endwisely slip on the input shaft 200 and be provided with input duplicate gear 1, endwisely slip on the output shaft 300 and be provided with output duplicate gear 2, be provided with transition axis 400 between input shaft 200 and the output shaft 300, transition axis 400 is provided with first duplicate gear 3 and second duplicate gear 4, described each gear all adopts the displacement spur gear, adopts split-type structural, the equal circular arc chamfering of gearshift face profile of tooth of each gear; Be provided with the input axis of guide 500 and the export orientation axle 600 parallel in the casing 100 with input shaft 200, endwisely slip on the input axis of guide 500 and be provided with input shift fork 5, endwisely slip on the export orientation axle 600 and be provided with output shift fork 6, described input shift fork 5 and 1 clamping of input duplicate gear, output shift fork 6 and 2 clampings of output duplicate gear are equipped with spacing collar 7 on the input axis of guide 500 and the export orientation axle 600.
Gearshift adopts the swing link type structure, can adjust the position of duplicate gear by stirring the external handle of casing, thereby reach the change of gear box ratio.Selector fork is radially positioned on the guide rod, and outdoor handle does not need to use very big strength can stir shift fork to carry out axial motion on guide rod when making gearshift, thereby finishes shift process.
Obviously; the foregoing description of the present utility model only is for the utility model example clearly is described; and be not to be qualification to mode of execution of the present utility model; for those of ordinary skill in the field; can also make other multi-form variation or changes on the basis of the above description; here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present utility model draws and still are among the protection domain of the present utility model.
